Which treaty with Russia aimed to reduce deployed strategic nuclear arsenals, signed during Obama's presidency?

• A. START I
• B. INF Treaty
• C. SALT II
• D. New START treaty

Answer: (D)

New START is the treaty signed in 2010 between the United States and Russia to curb deployed strategic nuclear weapons. It was crafted and signed during Barack Obama’s presidency and specifically aims to limit the number of deployed strategic warheads and the delivery systems that carry them. The agreement sets concrete caps—such as a maximum of 1,550 deployed strategic warheads per side—and places limits on deployed missiles and bombers, all tied to a robust verification regime that includes on-site inspections and regular data exchanges. This focus on reducing deployed strategic arsenals and ensuring verifiable compliance is what makes it the correct choice for a question about a treaty signed during Obama’s time in office.

Other treaties mentioned were signed earlier: START I dates to 1991; the INF Treaty to 1987; and SALT II to 1979. While these also address nuclear arms and limits, they were established before Obama’s presidency, not during it.
